This study aimed to evaluate the demographic and clinical characteristics of stroke cases in Murtala Muhammed Specialist Hospital, Kano, Nigeria. Five years of records of three hundred (300) stroke patients comprised of biodata and clinical data were collected. The data were expressed as mean±SD, while simple percentage and Chi-square (χ2) tests were used to determine the incidence and association between the variables respectively using Minitab 17.0 software. The results showed an incidence of 182 (61%) males and 118 (39%) females, 265 (78%) and 65 (22%) for the above and below 40 years age groups respectively. The Hausa, Yoruba and Igbo ethnic groups have an incidence of 258 (86%), 24 (8%), and 18 (6%) respectively. The yearly incidence was 40 (13%), 50 (17%), 20 (7%), 56 (17%), and 134 (45%) for 2017 through 2021, respectively.

The common risk factors were hypertension (50%) and hypotension (20%), diabetes mellitus 54 (18%), and others 12 (4%) and 3 (1%) respectively. No association between sex and stroke types (P = 0.553).
